HI, probaly a long shot but I think Wayne, Angus & RocketCityWriter may all be right - I have a Hummer Door from the movie Black Hawk Down. The door has numerous bullet holes from it's scenes in the movie, they drill out the hole (Angus), mount the firing squib (RocketCityWriter), cover and paint it up, then after the squib is fired during the scene, you are left with reasonably clean uniform "Bullet Holes" (Wayne). Maybe it was a practice piece for movie squibs. I'll take a couple of photos later and add themn(wife has been asking me to photograph it for ages, to stick on fleabay).

Looks like a piece of metal used to test countersink drill bits. Or maybe used in a metal shop class to teach how to use a drill press. The bullet hole thoery I don't think is even close. That many shots the piece would be warpped abd the spacing is too accurate.

I think it is made of reinforced stainless steel. I think the holes in it are made from bullets passing through the metal. I think this view depicts it from the rear because all of the holes look like exit wounds from a human skill...exploded perimeter. The shape leaves you wondering but I could envision two of these used in the chest plate of a bulletproof vest...the plates diminish in width as they descend toward the abdomen to allow some comfort when sitting. Obviously, this material, by itself would not be sufficient to line the vest but could it have some supportive resistant qualities as a plate surounding a heavier metal or glass substance...you tell me!

Lol, bullet holes...pretty clean for bullet holes :) I nearly agree with Angus on the drill holes, but I don't think they're practice. Notice that the 4 corner holes are all the same size and similarly all others are the same size as each other. This appears to be a mounting bracket for something...not sure exactly what though...Given the countersunk bolt heads would all be on the same side it appears you might be mounting two things on the back side of the object. Noting the finish, rounded edges, and odd shape I suspect this is a manufactured piece, not just something for practice.

awoodog is correct. As for anyone else that referred to a "stainless steel gusset plate"- Uh, I think NOT. Stainless has some of the worst tensile strength of any metal! The ONLY reason a stainless steel plate would be used as a gusset is for nuclear applications.

It's a support/gusset plate of some sort. It's specifically shaped and the holes make me thing it might have been in use for a while (judging by the width of the edges around the holes). Be interesting to find out what it truly is, and I wish you luck in getting your information.

Not having any dimensions anything would be a guess. looking at the shape and estimating a size of about 75 mm square, it may be a pedal for a car. but if you tell us what size it is we may be able to offer a better idea
